ATENT CRUPPER PRESS AND FORMER.

SPECIFICATION forming part of Letters Patent No. 34:5,143, dated July 6, 1886.

Application filed January 30, 1886. Serial No. 190,315. No model.)

T0 at whom it may concern:

Be it known that I, EDWARD W. J AOKSON, a citizen of .the United States, residing at Mount Kisco, inthe county of W'estchester and State of New York, have inventedcertain new and useful Improvements in Cropper Presses and Formers; and I do declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is aside elevation. Fig. 2 is a vertical longitudinal section. Fig. 3 is a top view. Fig. 4 is a detail view.

My invention has relation to presses and formers for pressing and forming cruppers for harness; and it consists in the construction and novel combination of parts, as will be hereinafter set forth, and pointed out in the claims.

Referring by letter to the accompanying drawings, A designates the bed-plate of the press and former, which is mounted on suitable legs, B, having feet B, provided with screwholes B", through which screws are to be passed to secure upon the work-bench or other desired support or stand. At one end the bed-plate A is made much thicker for a portion of its length, as at C, than throughout the remaining portion of its length, and this enlarged portion is grooved, as at D, around a horizontallyprojecting arm, E, which is formed integral with the enlarged or thickened portion 0. The groove D is partially lined with leather, F, which is secured in place by tacks. The rear face or end of the arm E is vertical, and to this vertical face G is secured a metal guardplate, H, which is similar in outline to the end of the arm E, but is considerably greater in area than the end of the arm E, so that the guard-plate H, which is secured in place by a screw, I, forms a flange along the curved line of the face G of the arm E. The bed-plate A is provided with a longitudinal middle groove, J, in its upper face, which extends from the inner end of the thicker portion 0 of said bedplate to the thinner end K of the bed-plate. This end K is provided with a metal bar, L, which is secured to the bed-plate by screws, so as to project slightly above the upper face of the bed-plate A. At its middle portion the metal barL is provided'with a hole, M, in which an unthreaded portion, M, of the jackscrew N rotates when said screw N is turned.

-The jack-screw N passes through a' threaded eye, P, on the under face of the clamp-frame Q, said eye 1? extending down into the groove J, so that when the screw N is operated the clamp-frame Q will be caused to move either toward or away from the thicker portion of the bed-frame, as may be necessary or desirable in operating the machine. The clampframe Q is provided with an integral jaw, Q, near its lower side, and this jaw Q, is grooved longitudinally in its upper face, in order that the leather may not slip when in place in the clamps.

R is a second removable plate, grooved longitudinally in its lower face,and provided with a depression, S, in its upper face, for the reception of the point of the thumb-screw T, seated in a threaded hole, U, in the arm Y of the clamp-frame Q. v

WV is the crupper-blank, which is first stitched and stuffed, placed in the groove D, the'ends of the blank then broughttogether and secured between the jaws of the clamp -frame. The jack-screw N is then turned, and the clampframe is caused to move away from the grooved former and draw upon and stretch the moist leather into the desired shape, after which the leather is permitted to dry in the former. When removed from the former after having been dried therein, thecrupper will always retain its shape. The wooden portion of the crupper-press is preferably made of oak; but any other hard wood may be used instead. Along the side of the middle longitudinal groove I provide metal wear-plates X, which extend from the thicker portion of the bedplate to within a short distance of the flange at the end of the plate. The jack-screw N is provided on each side of the flange, at the end thereof, with a loose collar, Y Y, the inner one, Y", being confined to its place by a cross IOO zontal jack-screw, and the clamp-frame having the threaded eye at its lower sideand the thumb-screw inits upper end, substantially as specified.

4. The combination, with the horizontal 2o grooved bed having the crapper-former at one end thereof, of the horizontal jack-screw and the clamping-frame connected therewith, sub stantially as specified.

In testimony whereof I affix m y signaturein z 5 presence of two witnesses.

EDWARD W. JACKSON.
